Hey John, thanks for taking the time to reply.
I think I can rule out the seeders issue, as this is the first thing I check when a download isn't working.
About not sharing files - right now I have about 2000+ finished torrents active ...
the issue remains, that I only exclusively have problems with torrents from this site 
there has to be an issue with some deeply hidden settings somewhere and I just can't figure it out
